You can pray the Novena delle Rose to ask for an important grace for you

PRAYER FOR THE NOVENA
Most Holy Trinity, Father, Son and Holy Spirit, I thank you for all the favors and graces with which you have enriched the soul of your servant Saint Teresa of the Child Jesus of the Holy Face, Doctor of the Church, during her twenty-four years spent on this land and, for the merits of your Holy Servant, grant me the grace that I ardently desire
(here we formulate the grace we want to receive),
if it conforms to your holy will and for the good of my soul.
Help my faith and my hope, O Saint Teresa of the Child Jesus of the Holy Face; once again fulfill your promise to spend your heaven doing good on earth, allowing me to receive a rose as a sign of the grace that I wish to obtain.

24 "Glory to the Father ..." are recited in thanksgiving to God for the gifts granted to Teresa in the twenty-four years of her earthly life. Each invocation is followed by the invocation "Saint Teresa of the Child Jesus of the Holy Face, pray for us".
